Moments later, the hidden camera team emerged to explain the whole thing was just one big joke - thankfully they all saw the funny side of it.

The prank was organised by Sky Living as part of their new three-part drama The Enfield Haunting.

It is based on the story of the 1977 Enfield Poltergeist, which made newspaper headlines worldwide after a number of witnesses claimed they experienced paranormal activity in a house in the London borough.

The prank, which was uploaded to YouTube on April 8, has now clocked up more than 251,000 views.
